Question
State SSS similarity criterion.
✓
Answer
SSS Similarity Criterion: If the corresponding sides of two triangles are proportional, then they are similar.
In $\triangle\text{ABC}$ and $\triangle\text{DEF},$ if
$\frac{\text{AB}}{\text{DE}}=\frac{\text{BC}}{\text{EF}}=\frac{\text{AC}}{\text{DF}}$
Then, $\triangle\text{ABC}\sim\triangle\text{DEF}$
In $\triangle\text{ABC}$ and $\triangle\text{DEF},$ if
$\frac{\text{AB}}{\text{DE}}=\frac{\text{BC}}{\text{EF}}=\frac{\text{AC}}{\text{DF}}$
Then, $\triangle\text{ABC}\sim\triangle\text{DEF}$
